    Matrix Algeba - Please help

    Hello I am working on an accounting problem using reciprocal method of allocation which is basically a matrix algebra. However, I cannot seem to solve the following.

    Please advise. I need to find what X, Y, and Z equal to.


    X Y Z
    X .2 .1 .2
    Y .4 .1
    Z .0909

    COST
    X 100,000
    Y 50,000
    Z 40,000


    So I am assuming the first function is: X=100,000 + .2X + .4Y
    I am not sure if this is correct. Should it be X=100,000 + .4Y

    Please advise as to how to solve this problem.

    Thank you for any help or guidance.

    Your question is gobbledy-gook to me. I don't see any way of coming up with equations from your statement of the problem. Could you please state the original problem, word-for-word? Thanks!
